Eligibility criteria
Principal inclusion / exclusion criteria as submitted by sponsor
Inclusion criteria 1
- Patients with suspected GPSD. In order to be eligible to participate in this study, a subject must meet all of the following criteria: - Age ≥ 50 years - Patients must be able to adhere to the study appointments and other protocol requirements. - Patients must be capable of giving informed consent
Exclusion criteria 1
- Patients with suspected GPSD. A potential subject who meets any of the following criteria will be excluded from participation in this study: - Suspected GPSD, - Presence of symptoms, imaging test result or biopsy findings suggesting cranial artery involvement in GPSD (‘cranial giant cell arteritis’) - Use of oral glucocorticoid treatment or disease modifying anti-rheumatic drugs at time of inclusion - Females with child bearing potential. Post-menopausal women with >12 months of amenorrhoea are considered to have no child bearing potential. Given the age distribution of patients with GPSD, exclusion of females with child bearing potential will not lead to recruitment bias in the study. - Research-related radiation exposure (cumulative ≥5 mSv) in the year before inclusion.
